When the flow medium flows through the measured tube, the pressure will force on the target because of the flow kinetic energy. It is known that the pressure value forcing on the target can be expressed as： F = cd ρ v2 At / 2 where F = force on the target (N) cd = overall drag coefficient obtained from empirical

Usually, the Target flowmeter display unit has the following options: flow unit m3 flow unit t flow unit L flow unit Kg

In many instances, yearly calibrations are not necessary. If the measurement requirements are high, there are more impurities and dirt in the fluid, and the environmental conditions are poor, the electrode is fouled, which affects the measurement, cleaning, and the measurement is inaccurate after repair. It can be calibrated. If the working conditions are good

The flowmeter should generally be installed behind the valve, because the medium may appear two-phase after passing through the valve, the pipe is not full, and the flow phase is unstable. These conditions will greatly affect the measurement accuracy of the flowmeter, so the flowmeter should be installed in front of the valve. But because

Although the flow meter has been strictly tested before leaving the factory, because of changes in the environment, installation, running condition, etc, errors will occur, and test operation needs to be done using the following methods: Test using standard flow measure equipment Conversion between two flow media The primary test medium in the factory is

When choosing a magnetic flow meter, the following factors may take into consideration: 1 Fluid types 2 Accuracy 3 Density 4 Viscosity 5 Electrical conductivity 6 Contaminants 7 Flow range 8 Fluid temperature 9 Fluid pressure 10 Pressure loss 11 Pipe diameter   You can also download this checklist form.   https://drive.google.com/file/d/1bUdTYPWLu25eJf1orMPRe5vnZnCF9Dr7/view?usp=sharing

Target Mode Flow meter consists of measure tube, pressure target, sensor part (include flow strength sensor, pressure sensor, and temperature sensor), transition part (variable types based on temperature, pressure), integration microcomputer (include an LCD display and output part). The structure is shown below: Target Sensor Part Measurement Tube Transition Part Integration Microcomputer

Target flow meter usually installed after the pump. As there should be no excessive pressure drop at the pump inlet (in front of the pump). Installed a flow meter will always increase the pressure drop. It may also increase the length of the pipe and increase the complexity of the pipe. Moreover, the pipe in

Although the flow meter was set zero before leaving the factory, it may be offset because of the inevitable slight impact on transport. If the flow meter does not display zero when the flow velocity is zero, zero offsets occur and zero set operation has to be done: Close the behind valve. Turn on the
